Overview
ℹī¸
Collinder 463 is a very rich, moderately dense object of very high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Almeida et al. (2025)
Mass determination: good fit. Isochrone match: good fit. Gold sample.

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Hu et al. (2021)
Ellipticities (core, all): e_core=0.219, e_all=0.2591.

Rain et al. (2021)
This cluster was include in (Dias et al., 2002A&A...389..871D, Cat. B/ocl) however, parameters log(t)=8.427, Av =0.836, [Fe/H]=0.00 were taken from Bossini et al. (2019A&A...623A.108B, Cat. J/A+A/623/A108). The distance d=789.8 (dmode+01) of Cantat-Gaudin et al. (2018A&A...618A..93C, Cat. J/A+A18/A93) was use to fit the isochrone.
